Experiments promote a curious flipside of decaying monopoles: A reality where particle physics is quite literally turned on its head. The field of quantum physics is rife with paths leading to tantalising new areas of study, but one rabbit hole offers a unique vantage point into a world where particles behave differently — through the proverbial looking glass.

Dubbed the ‘Alice ring’ after Lewis Carroll’s world-renowned stories on Alice’s Adventures in Wonderland, the appearance of this object verifies a decades-old theory on how monopoles decay...

With the help of computer simulations, particle physics researchers may be able to explain why there is more matter than antimatter in the Universe. The simulations offer a new way of examining conditions after the Big Bang, and could provide answers to some fundamental questions in particle physics.

In the Standard Model of particle physics, there is almost no difference between matter and antimatter. But there is an abundance of evidence that our observable universe is made up only of matter – if there was any antimatter, it would annihilate with nearby matter to produce very high intensity gamma radiation, which has not been observed...
